Moves the scheduling surface — 5 delivery actions (schedule_task,
cancel_task, pause_task, resume_task, update_task), handleRecurrence,
applyPreTaskScripts, and task DB helpers — out of core and into
src/modules/scheduling/ (host) and container/agent-runner/src/scheduling/
(container).
First PR to fill the MODULE-HOOK markers introduced in PR #2:
- src/host-sweep.ts MODULE-HOOK:scheduling-recurrence now dynamically
imports handleRecurrence from the module each sweep tick.
- container/agent-runner/src/poll-loop.ts MODULE-HOOK:scheduling-pre-task
dynamically imports applyPreTaskScripts before the provider call.
When the marker block is empty (scheduling uninstalled), `keep`
falls back to `normalMessages` so non-task messages still flow.
The 5 task cases are removed from delivery.ts's handleSystemAction
switch — the registry now routes them. Task DB helpers moved out of
src/db/session-db.ts (which kept `nextEvenSeq` as a named export so
the module can uphold the host-writes-even-seq invariant). Test suite
split to match: scheduling-specific tests live in the module.
No migration — tasks are messages_in rows with kind='task'.
